Does this guide apply to your appliance?

Match the brand, device type and complete display code. The same code can mean something different on another product family or market; a series name does not confirm every model in that series.

AEG LavamatAEG 7000 Series ProSteamAEG 8000 Series ÖKOMixAEG 9000 Series SensiDry

Likely causes

  • Water supply tap closed, disconnected, or mains water pressure too low
  • Inlet hose mesh filter clogged with limescale, sand, or debris
  • Water inlet or drain hose kinked, squashed, or restricted
  • Incorrect drain hose installation height or siphonage issue
  • Excess detergent foam blocking the internal pressure-sensing level system
  • Blocked drain pump or fluff filter

What to try

Check Water Supply and Clean Inlet Hose Filters

Easy
  1. Ensure the water supply tap connected to the washer dryer is fully turned on.
  2. Turn off the appliance and unplug the power cord from the electrical socket.
  3. Shut off the water tap and unscrew the inlet hose from the tap.
  4. Inspect the small mesh filter inside the inlet hose connector and clean it under running water to clear limescale or grit.
  5. Check and clean the filter inside the machine's rear water inlet valve where the hose attaches.
  6. Reconnect the hose tightly by hand (do not overtighten with tools) and reopen the water supply to verify water flows without leaks.

Inspect Drain Hose Setup and Reduce Foam

Easy
  1. Check behind the appliance to confirm neither the inlet hose nor the drain hose is kinked, pinched, or twisted.
  2. Verify the drain hose height is between 60 cm and 100 cm above the base of the machine.
  3. Ensure the end of the drain hose does not extend more than 10 cm into the standpipe or waste connection to prevent siphoning.
  4. If heavy foam is visible due to detergent overdosing, turn off the machine and allow foam to dissipate to prevent sensor blockages, then run a hot maintenance rinse without detergent.

Reset the Washer Dryer and Run a Test Cycle

Easy
  1. Unplug the machine from the electrical outlet.
  2. Wait 30 to 60 seconds to allow the control electronics to reset fully.
  3. Plug the power cable back into the wall outlet and power on the unit.
  4. Start a short rinse or wash cycle to check if the machine fills and drains properly.
  5. If error code C1 reappears, disconnect power and contact an authorized AEG service technician to inspect the water inlet valves or electronic control board.

The code returned or the check did not help?

Avoid repeated resets and do not select a replacement part from the code alone. Record the exact code, full model number, when it appeared, and the checks you tried with their results. Share these details with the manufacturer or service technician.

Disconnecting power does not establish that internal components are safe to touch. This guide does not authorize opening electrical components or bypassing safety devices.
